Hi All,

I upgraded my IPhone to 6.1, but no service. please help! many thanks.
 
Could you try resetting your phone to its manufacture settings? I'm thinking maybe that will put a previous OS back on the device. Of try unlocking the phone and put a prior OS on it.

This makes no sense at all.

@trunghieu007, was your device previous unlocked using any method at all like UltraSn0w. If you were software unlocked on your 3GS, you'll need to put the software unlock back onto the device if you're using a carrier that's not the original carrier of the device
